Activity of neutrophil NADPH oxidase in iron-deficient anemia.

This study was designed to measure the effects of iron supplementation on respiratory burst in iron-deficient anemia. The performance of neutrophils was evaluated by measuring the activity of NADPH oxidase in 18 patients with iron-deficient anemia before and after body iron stores are saturated. The activity of NADPH oxidase was significantly lower in pretreatment patients relative to controls (p<0.05). The activity increased after iron supplementation to levels that had no significant differences relative to controls.
